As shown in FIG. 1, the binding device 10 includes a substrate 12 having a substantially convex shape in plan view. The base material 12 is fixed to a file cover H made of synthetic resin. As a fixing method,
A method such as ultrasonic welding or high frequency welding can be used, and an adhesive, eyelet fittings or the like may be used.

The substrate 12 is provided on both sides in the longitudinal direction of the substrate 12.
A pair of elongated strip-shaped pieces 14 are integrally formed therewith. One end of the strip 14 is a free end. The strip 14 is inserted through the binding hole Ph formed in the document P to be bound. The strip 14 of this embodiment has a substantially L shape when viewed from the side.
It has a bent shape, and is formed so that, in a normal state, it projects substantially vertically from the base material 12, and then extends to both outer sides in the longitudinal direction of the base material 12 in parallel with the main surface of the base material 12. Since the strip 14 is made of the same material as the base material 12 and has flexibility and elasticity, the strip 14 is inserted into the binding hole Ph of the document P. Therefore, as shown in FIG. Can be bent and stretched so as to extend at an angle of about 45 ° with respect to the main surface of the base material 12, and then return to the original substantially L-shape shown in FIG. 3 due to the restoring force based on elasticity. Therefore, the document P does not come out of the strip 14.

On the surface of the strip-shaped piece 14 facing the file cover H shown in FIG. 1 on the free end side thereof, there is a linear recess extending linearly from the tip of the strip-shaped piece 14 toward the substrate 12 by a predetermined length. 16 is integrally formed. The grooved portion 16 constitutes a part of the locking member of this embodiment. Groove 16
Is formed to have a substantially concave cross-section, and is used for detachably fitting a ridge portion 28 described later. This groove 1
6 is opposed to the upper surface of the holding member 16 during use.

The spline hole Ph of the document P is a root portion of a substantially L-shape including a portion of the strip-shaped piece 14 in which the recessed portion 16 is not formed, that is, a portion protruding substantially vertically from the base material 12.
It is used as a binding body 14a for engaging with. The length of the binding body 14a maximizes the thickness of the document P that can be bound in the binding tool 10.

A flat strip-shaped hinge member 18 is integrally formed on one end side of the base material 12 in the widthwise direction. Hinge member 1
8 is arranged to extend in the thickness direction of the document P to be bound so that the thick document P can be bound. Further, the hinge member 18 is formed with three folding curves 20 extending from one end to the other end in the direction orthogonal to the bending direction. 3 folding curves 20
Are thinly formed by being respectively recessed in a substantially U-shaped cross section from both outsides in the thickness direction of the hinge member 18. In addition, substantially U-shaped through holes 21 are formed near both sides of the hinge member 18 in the longitudinal direction.

On the opposite side of the hinge member 18 from the substrate 12, a sandwiching member 22 is integrally formed with a folding line 20. The holding member 22 is arranged to face the base material 12 by being folded back by the hinge member 18, and holds the document P to be bound with the base material 12.

On the opposite side of the holding member 22 from the hinge member 18, when the holding member 22 is bent on the base material 12, the positions substantially corresponding to the two strips 14 are respectively held as shown in FIG. The member 22 is cut out into a substantially right-angled triangular shape as seen from a plane so as to extend from the edge portion to the hinge portion 18 side.
Two notches 24 are formed. The cutout portion 24 includes an insertion portion 24a through which the binding member 14a on the base side of the strip 14 when fastened by the protruding portion 28 and the recessed portion 16 as locking means is inserted. The insertion portion 24a is a substantially rectangular through hole that is formed inside and adjacent to the protruding portion 28. In addition, the cutout portion 24 is continuous with the insertion portion 24a and the insertion portion 24a.
An introduction portion 24b that extends obliquely at an angle of approximately 45 ° in plan view with respect to the longitudinal direction of the sandwiching member 22 is provided so that the notch width increases from a toward the outside of the sandwiching member 22. In other words, the introduction portion 24b of the cutout portion 24 is formed such that the cutout width gradually narrows from the outer side of the holding member 22 toward the inner insertion portion 24a. Here, the cutout width is the distance between the introduction portion 24b of the cutout portion 24 and the facing portion 24d facing the longitudinal direction of the holding member 22. Introductory part 2
4b is for making it easy to introduce the strip 14 into the insertion portion 24a. In this embodiment, the facing portion 24
As shown in FIG. 1, d extends perpendicularly to the longitudinal direction of the holding member 22, but is not limited to this, and the facing portion 24d also holds the holding member 22.
It may be formed so as to be inclined with respect to the longitudinal direction, and the notch width may be further expanded outward from the insertion portion 24a.

Further, as shown in FIG. 2, the edge portion of the introduction portion 24b of this embodiment is arranged in the thickness direction with respect to the main surface of the file cover so that the cutout width is expanded from the file cover side to the opposite side in the thickness direction. As a result, an inclined wall 24c is formed which is inclined in a slope shape at an angle of about 45 °.

Further, both outer sides of the two notches 24 in the longitudinal direction of the holding member 22 are formed in a flat plate shape.
Then, the ridges 28 are formed so as to protrude from the main surfaces and bulge into a substantially T-shape having a rounded cross section. The ridges 28 serving as the engaging members of this embodiment are formed in a rail shape extending linearly from both longitudinal ends of the holding member 22 to the vicinity of the insertion hole 24a of the cutout 24. The ridge 28 is for detachably fitting with the ridge 16 of the strip 14. This spelling tool 10
Then, the concave streak portion 16 and the convex streak portion 28 constitute a locking means. In this case, since the groove 16 of the strip 14 is made of a material having flexibility and elasticity, when it is pressed against the tip of the protrusion 28 and pressed, the groove 16 is opened so as to be opened. When the ridges 28 are subsequently pressed and fit into the concave ridges 16, the ridges 16 are restored to their original shape by the elastic force and are fixed to the ridges 28. In this state, unless the user applies a force in the direction in which the ridge portion 28 and the ridge portion 16 are separated from each other, the ridge portion 28 and the recessed portion 16 are firmly fitted to each other without separating. When the user applies a force in the direction of separating the convex portion 28 and the concave portion 16, the fitting between the two is released by the action opposite to the above.

The hinge member 18 of the binding device 10 fixed to the file cover H is bent at a folding line 20 and is arranged so as to extend from the base material 12 in a substantially vertical direction. When the strip 14 is inserted into the binding hole Ph, the strip 14 is bent and straightened so as to extend in a direction substantially perpendicular to the base material 12. Then, the free end of the strip 14 is inserted into the binding hole Ph formed in the document P. After that, the strip 14 is
The elastic force urges the base material 12 outward in the longitudinal direction,
As shown in FIG. 3, the shape returns to the original substantially L-shape. Next, the holding member 22 is bent by the hinge member 18 and arranged so as to face the base material 12 and is brought into contact with the document P. Then, as shown in FIG. 4, the strip 14 is bent and stretched at about 45 ° and guided from the introduction portion 24b of the notch 24 along the inclined wall 24c to the insertion hole 24a. Then, the free end of the strip-shaped piece 14 extends upward from the insertion hole 24 a of the cutout portion 24.
Then, the free ends of the strip-shaped pieces 14 are bent toward both outer sides in the longitudinal direction of the base material 12, and the ridges 16 and the ridges 28 are formed.
By fitting and, they are fastened on the holding member 22. As a result, the document P is sandwiched between the sandwiching member 22 and the base material 12, the document and the like are prevented from slipping out of the strip 14, and the document P is prevented from slipping out of the binding device 10 without permission. Further, when the document P is taken out from the binding device 10, the user hooks his / her fingertip on the obliquely formed portion of the tip of the strip 14 and applies a force in a direction of separating it from the holding member 22. Then, the ridge portion 28 and the ridge portion 1
The fitting with 6 is released. Then, contrary to the above, the strip 14 is inserted from the insertion hole 24a of the cutout portion 24 to the inclined wall c of the introduction portion 24b.
The user can pull out the document or the like from the free end of the strip-shaped piece 14 by separating the holding member 22 from the surface of the document P while pulling it out of the holding member 22 along the line.
